I have a 92 Civic Si with a built Gsr motor. I'm breaking freah motor in on stock parts..ecu,injectors and etc. I'm still using resistor box and running 88-91 crx si injectors but not getting any spark what so ever in any cylinder. I switched out distributors but nothing and switched to a stock P28 ecu and nothing. I'm getting a cel# 15 which is ignition output signal but don't know what it can be. Any help would be greatly appreciated.

 

Have you checked continuity in your wiring between the distributor & the ECU? The code is saying the ECU can't see the ignition signal coming from the distributor. You already tried another distributor (sure it was good?) so what's left but the wiring?

Make sure you get +12v from the main relay; I don't know offhand which terminal at the distributor. Then make sure each of the other connections is intact.

 

it was a bad distributor. The one i switched it with had an msd on it thats y it didn't work either. For some odd reason a few wires were apart in my distibutor. Thanks for the help though.
